Interviewed by Sky News alongside a military tank, the fast food retailer said he felt just as much at ease handling a Kalashnikov rifle as he does running a shop.

Mr Abudullah said: "Actually, I've got a British passport, I've got everything, I've got a life there, I don't need anything but I'm here just for Kurdistan, for Kurdish people, for my family. I don't care if I get killed or not."

Mr Abudullah and his friends took film footage of the battle with Isis in Jalula, northern Iraq. At one stage the Peshmerga are pinned down in a doorway while shots ring out outside. In other footage, the Peshmerga are fighting to keep Isis out of the courtyard of a mobile phone tower.

Mr Abudullah looks uncomfortable as the Peshmerga risk being overwhelmed by much more experienced, much better armed, Isis opponents.

Mr Abudullah said: "My friends have been killed next to me. If people were killed next to you, you are going to be happy? No.
